I know, I have spent hours sending in false positives to many virus companies to try and get the files excluded, but to be honest I would need the rest of my life to achieve it. If Avast has a submit button I would appreciate you submitting them as eventually it would help some other Mesh user in the future. It's like they've run out of things to do, they started on the SE modules a couple of years ago en-masse. Some of my code has been around for 5-6 years and the dll unchanged in all that time, yet suddenly it is malicious. To be honest it's the main reason I've stopped developing VST plugins for the moment, somebody downloads a demo, sees a virus warning, removes it and never comes back to your site, the damage it has caused me is massive. Oh well, such is life

https://support.avast.com/Tickets/Submit-That's the Avast false positive reporting page, I use it every now and then and they get it off the list in 2-3 days time. You don't need it installed, just say you have the free version.
